To obtain the enhancements, follow the steps described in Apply maintenance updates.

Restriction of RADOS Gateway capabilities

To improve the product security, restricted the RADOS Gateway capabilities to a bare minimum. For the existing environments, perform the steps described in MCP Operations Guide: Restrict the RADOS Gateway capabilities.

Ceph Nautilus support

Introduced support for the Ceph Nautilus 14.2.6 release. The major enhancements include the Messenger v2 protocol and the ceph-volume tool. Added full support for the ceph-volume tool that is now enabled by default for new MCP deployments. For the existing deployments, enable the ceph-volume tool before upgrading Ceph from Luminous to Nautilus.

RBD monitoring


Implemented the capability to monitor RADOS Block Device (RBD) images using the Ceph RBD Overview Grafana dashboard. RBD monitoring requires Ceph Nautilus and is disabled by default.
